New in version 3.18.
It is not allowed to create an ALIAS
target with the same name as an
another target.
In CMake 3.17 and below, an ALIAS
target can overwrite silently an existing
target with the same name.
The OLD
behavior for this policy is to allow target overwrite.
The NEW
behavior of this policy is to prevent target overwriting.
This policy was introduced in CMake version 3.17. Use the
cmake_policy()
command to set it to OLD
or NEW
explicitly.
Unlike many policies, CMake version 3.19.8 does not warn
when this policy is not set and simply uses OLD
behavior.
Note
The OLD
behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
